IEEE 802.3 is a working group and a collection of standards defining the physical layer and data link layer's media access control (MAC) of wired Ethernet.The standards are produced by the working group of the Institute of Electrical and Electronics Engineers (IEEE).
Everything above LLC is explicitly out of scope for IEEE 802 (as "upper layer protocols", presumed to be parts of equally non-OSI Internet reference model). The most widely used standards are for Ethernet , Bridging and Virtual Bridged LANs, Wireless LAN , Wireless PAN , Wireless MAN , Wireless Coexistence , Media Independent Handover Services ...
EtherType values are also used in Subnetwork Access Protocol (SNAP) headers. Ethernet is widely used in homes and industry, and interworks well with wireless Wi-Fi technologies. The Internet Protocol is commonly carried over Ethernet and so it is considered one of the key technologies that make up the Internet.
Examples of data link protocols are Ethernet, the IEEE 802.11 WiFi protocols, ATM and Frame Relay. In the Internet Protocol Suite (TCP/IP), the data link layer functionality is contained within the link layer , the lowest layer of the descriptive model, which is assumed to be independent of physical infrastructure.
EtherType is a two-octet field in an Ethernet frame. It is used to indicate which protocol is encapsulated in the payload of the frame and is used at the receiving end by the data link layer to determine how the payload is processed. The same field is also used to indicate the size of some Ethernet frames.
IEEE 802.1Q, often referred to as Dot1q, is the networking standard that supports virtual local area networking (VLANs) on an IEEE 802.3 Ethernet network. The standard defines a system of VLAN tagging for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames.
G.hn defines an Application Protocol Convergence (APC) layer that accepts Ethernet frames and encapsulates them into G.hn MSDUs. Other networking standards do not use the Ethernet frame format but can still be connected to Ethernet using MAC-based bridging. 802.11—Standards for wireless local area networks (LANs), sold as Wi-Fi
The purpose of this project is to extend the 802.3 protocol to operating speeds of 40 Gbit/s and 100 Gbit/s in order to provide a significant increase in bandwidth while maintaining maximum compatibility with the installed base of 802.3 interfaces, previous investment in research and development, and principles of network operation and ...
